IMPROVEMENT IN BRICK-KILN S.

Specification forming part of Letters Patent No. 181,399, dated August 22, 1876 application filed June 17, 1876.

To all whom it may concern:

Be it known that 1, EDWARD W. BINGHAM, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and val uable ImprovementinBrick-Kilns; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

The drawing is a representation of a perspective sectional view of my improved kiln.

This invention has relation to kilns and it consists in the construction and novel arrangement of the exterior furnaces in immediate contact with the kiln-wall, which forms the rear walls of the furnaces, and of the curved or bent eyes in the kiln-wall, whereby several eyes may be made to communicate with a furnace of small width built against the side of a kiln of the rake holes in the furing into the furnace, and of a kiln having such exterior furnaces built against its outer walls, as hereinafter shown and described.

In the accompanying drawings, the letter A designates one of two vertical side walls of a kiln, and B a furnace built against this wall, so that a section, a, thereof forms the rear wall of said furnace. O 0 indicate the side walls of the furnace, and D its front wall, in which is usually located the doorway E. F'is the grate, built about nine inches below the bottom of the kiln-eyes, and provided underneath with an ash-pit, G. The drawings illustrate a furnace with four eyes of the kiln-wall communicating. Two of these eyes, I) b, are designed to openinto the furnace through its rear wall a, which is a section of the wall of the kiln, as above stated. Between these eyes a wedge-shaped column, 0, of the kiln-wall is built up, whereof the broader side is turned toward the interior of the kiln, to correspond with the mass of bricks or other ware between the arches into which the eyes lead. The

openings or portions 1), which lead into the arches are designed to run in a direction perpendicular, or nearly so, to the interior face of the kiln-wall, so as to be in line with the arches. The bottoms of these eyes are raised a little above the level of the grate, which is laid in a horizontal position, as shown in the drawings. On each side of these two eyes is arranged an eye, d, which is divided from its adjacent eye I) by building in the kiln-wall a wedge-shaped column, 6, around which the eye at extends in such a manner that while its interior portion cl enters the kiln in the direction, or nearly in the direction, of the kilnarch the furnace end 0 is brought throughthe side wall 0 of the furnace a short distance in front of the kiln-wall a, which forms its rear wall. This bent-eye passage, therefore, extends through the side wall of the furnace, which is expanded at G to receive it. H indicates the arched top of the furnace, which issprung transversely from side wall to side wall, as shown in the drawings.

Through the front wall D of the furnace extend the rake-holes g. These are so built that their exterior walls. will be in line with the eyes b on the same side of the furnace,

while their interior walls next the furnace- ,doorwill be somewhat oblique in the direction of the eyes I) of the opposite side. In this manner theseholes serve to ascertain the condition of the arches of the same side, and to fake the eyes b of the opposite side. For the eyes d oblique rake-holes h are made through the side walls 0, and peep-holes k are built through the bent exterior walls 1 of said eyes, as shown in the drawings. 7

This construction may be varied by building a central eye through the kiln-wall section a, and omitting the central wedge-shaped column, running the rear eye straight. With the lateral bent eyes the furnace will now be adapted to serve three arches of the kiln or, the central bent eyes I) b may be omitted entirely, in which case the furnace will be adapted to serve two arches of the kiln. v

The bent eyes are designed to effect a saving of material in building the kiln and furnaces, and to enable the depth of the furnaces to be reduced, as the drafts of air entering the same will be directed against the walls of the eyes, their temperature raised, and: their mixturewith the heated gasesyfrom the furnace facilitated.

What I claim as new, and desire towsecure by Letters Patent, is-- 1. The combination, with a vertical kiln-wall section, a, forming the back of a furnace, and. having one or more eyes opening through it, of the bent side eyes 6 6, opening through the side walls 0 G of said furnace, substantially as specified.

2. The combination, with a kiln-fiurn ace having eyes opening angularly into itsrear portion, of the oblique rake-holes in the walls of said furnace opposite said-eyes to facilitate opening and closing the same, substantially as specified.

3.. The combination, with the-sidewalls O Oof a kiln-furnace, of. the obliquely-placed.

openings or mouths h of the bent lateral eyes d, whicl1 extend through the kiln-wall to the hereunto subscribed my name in the presence of two witnesses.
